Consider the customer's needs and improve service quality


In line with the philosophy of meeting user needs and providing better service, after careful consideration, our company has decided to begin upgrading the RS-I type locomotive variable frequency air conditioning systems used by the first batch of users (Nanchang Railway Bureau) free of charge from June 5, 2003. The system will be replaced with the RS-III type. This measure has been unanimously praised by users and has established a good image for our company's After-sale Service!
